In spite of it only having 12 billion instead of the minimum recommended 15 billion. And in spite of it having only 4 varieties of bacteria instead of 8 or 15 varieties, it does work for us with diaharea.
Another brand with 20 bilion and more varieties did not work as well.

Have used Country Life Power Dophilus now for about a year. Best benefit is that I was lactose intolerant before using it... can now have anything with milk in it, including ice cream. I don't know if this works this way for everyone, but for me it has taken away the fear of eating cheese and eating things on the creamy side.
